Are algorithms like AES or WHIRLPOOL supported in jasypt?
Yes and no. Jasypt by itself does not implement any algorithms, but it lets you use any JCE provider of your choice. Both AES (encryption) and WHIRLPOOL (digests) are algorithms supported by the Bouncy Castle JCE provider, and thus you can use them from jasypt as long as you set Bouncy Castle as your JCE provider for your jasypt encryptors or digesters.
